Dear all,

I have set up a xcopy batch job that is copying data from a Windows machine to MacOS fileshare. It uses the /MIR Parameter it's one way direction. Only changed files from Windows to Mac are subject to be copied, in case differ in size or stamp.

I do experience now, that by running this job multiple times, xcopy comes to conclusion while comparing files, that the files on HFS+ Target Share have been changed and differ to the source. So approx. 25% of my files are copied to the Mac-fileshare again.

This is not efficicent, wastes bandwidth, and I even do not see the root cause why files on HFS+ have changed. Does MacOS touch files by default or while they are indexed/thumbnailed?

I know this error is not with xcopy, because as soon as target is changed to a Linux Samba Share, everything works fine and even after multiple xcopy-Runs, it always rates formely copied files as unchanged on the Linux share.

Does someone has an idea how to avoid MacOS altering files in background?

Your help is much appreciated here :)
